AlbertaWX – Central Alberta Storm Chasers

After yet another cold April we may not see the 30C+ weather that usered in May of 2013. In fact we are about to break a 4 year break form May snowfall here at ALbertaWX. Acumulating snow is expected early next week, though not the kind of snow dumps we saw in 2010(last time it snowed in May) But this time coming with not just a few days but a whole week of temperatures up to 10C colder than normal, such has not been seen this time of year since 2003. Due to extreme patterns in the jet stream so late in the year it is likely May 2014 will continue to see weather extremes much like 2010 where near 30C temperatures were followed by heavy snow just a few days later.

Here is my May 2014 forecast, Only a few more weeks an we might be seeing our first severe WX of 2014.

Starting tonight and lasting partly into Wednesday amounts of 30-70mm are expected to fall over a large part of Alberta. The significance of this system is the time of year. All time records for a singly day rainfall in April are lower, around 25-50mm. This means that the forecast amounts are record breaking.

I’ve made this map to show where I believe the heaviest rain could fall. The Drayton Valley, Pigeon Lake area could see the most

While climate Data seems to be hard to find I have found a few sites in the heaviest rains that may set a new monthly 24 hour rainfall record. In which the forecast is within 5mm or is experted to exceed the record

Edmonton intl: 43.4mm set on the 23rd of April 1990(daily plus monthly record)

Edmonton City centre: 27.2mm set on the 20th of April 1940

Camrose: 22.1mm set on the 30th of April 1951

Stony plain: 40.2mm set on the 23rd of April 1990(daily plus monthly record)

Wetaskiwin: 21.6mm set on the 23rd of Arpil 1990(daily plus monthly record)

Nordegg: 21.2mm set on the 24th of April 1983

Red Deer: 48mm set on the 30th of April 1951

Whitecourt: 24.2mm set of the 24th of April 1991

Stay tune for more updates. EC will likely issue a summary of the if records are broken.
